摘要

靖平2井是长庆石油勘探局独立完成的第1口水平井,由于该井优化井身结构,简化施工程序,造斜点低,靶前距短,水平段长,施工难度大,因此采用了防斜快钻技术。详细介绍了靖平2井的地质情况与井眼轨迹设计,斜井段轨迹控制方面的难点、要求和措施,给出了取得的技术成果和几点建议。

Abstract

Well Jingping-2 is the first horizontal well drilled by Changqing Petroleum Exploration Bureau independently. As this well has special casing program, low kick-off point, short distance of hitting target, and long horizontal interval, field operation is very difficult, and thus deviation control fast drilling technology is applied. The geological condition and well trajectory control, especially trajectory control in the deviated interval, its difficulties, requirements and solving measures are described in detail. The technical achievements in drilling this well, and some recommendations are also presented in this paper.
